Arc tabular, and inner side both ends are respectively equipped with the first energy-absorption box；The fire-proof and explosion-proof mechanism includes arc-shaped block support
Seat, the support base outside on the inside of back buffer beam outside plate with being close to, and inner side is equipped with two symmetrical second energy-absorption boxes, and both ends are supported respectively
By two first energy-absorption boxes, and matched arc head cover is equipped with the top of support base, the support base top surface offers downwards
The arc groove being adapted with its shape, the arc groove is interior to be equipped with matched rubber cushion blocks, the rubber cushion blocks
Top surface offers downwards " V " type groove, and the interior space in addition to rubber cushion blocks of the arc groove is described filled with fire prevention liner
First energy-absorption box and the second energy-absorption box are respectively arranged in mounting bracket；It is symmetrically arranged that the safety protection mechanism includes two
Air bag device, the air bag device include sequentially connected impact microphone, control module and airbag inflated
Module, the impact microphone are arranged in back buffer beam outside plate, and the airbag inflated module is arranged on the first energy-absorption box
Top.
Further, the fire prevention liner is dry powder.
Further, triangle cushion block is further included.
Further, the triangle cushion block is arranged on mounting bracket side.
Compared with prior art, the beneficial effects of the present invention are：Using fire-proof and explosion-proof mechanism, when receiving shock, branch
Support seat is squeezed and so that rubber cushion blocks are squeezed, due to employing " V " type groove at the top of rubber cushion blocks, in rubber
When receiving extruding before and after cushion block, the fire prevention liner of filling can be allowed quickly to spray upwards so that fire prevention liner effectively sprays after shock
It is sprinkled upon on the bonnet for the vehicle that knocks into the back, prevents the generation of fire dangerous situation；Using airbag inflated module, after shock, substitute
Capsule can be ejected quickly, be filled in and knocked into the back between vehicle and the cargo that is knocked into the back, effectively play cushioning and protection, be protected
Knock into the back the passenger safety of vehicle.

Embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.
As shown in the figure, a kind of back buffer beam assembly for cargo, installed in the 11 tail end bottom of compartment of cargo
Portion, including back buffer beam outside plate 1, fire-proof and explosion-proof mechanism 2 and safety protection mechanism 3, back buffer beam outside plate 1 are in middle part outwardly convex
Arc tabular 1, and inner side both ends are respectively equipped with the first energy-absorption box 4；Fire-proof and explosion-proof mechanism 2 includes arc-shaped block support base
21, the outside of support base 21 is close to the inner side of back buffer beam outside plate 1, and inner side is equipped with two symmetrical second energy-absorption boxes 5, and both ends are supported respectively
